TO ALL WHOM IT MAY CONCERNE I Be it known that I, HERVEY D. SNOW, of'Benningt'ou, in the cou-ntyof Bennington; and Stateot'- Vermont,

have invented and made a ,certain new and useful Improvement in- Water-Wheel Regulators-gf" and Ido'hereby declare the followingto be a full, clear, and exact description of the said invention, reference being had-to. the

onnexo'd drawings, makingpart ci' this specification, whereinl i :Efigure Iisanelevation at one side of said regulator,

Figure 2 is an elevation o f the same at the other side, the shaft bein'g'in section, l atfthe liuogfy, iig. 3, and

Figure@ is a sectional plan, at the linea; m, iig. l. Similar marks of reference denote the same parts.

The nature of' my said invention consist-s in peculiar mechanism applied between agovernor (operating by a cliangel speed) and the' gate or device for regulating the {iowof Water to the wheel, said mechanism beingvinoperative while the speed reroains at the regular standard, and being-brought into action by an increase 0 1" decrease ci" -the speed, to admit more or less Water to the wheel, and adjustable stops are applied'to said mechanismrto preventthe supply of water being entirely shut ofi`, o1 the gate'openecl to'ojvide.

By nywlelvic'e there is no risk of the governor operating too for in over-charging the wheel, or cutting o toomnch of the supply before themornentum of the parte allows the governor-to act; hence the speed is much more uniform than h'erjet'oftne.`

-In the drawing, a is a shaft set in standards Z, and extending-to and connected with the device that acts` upon the .gate or other regulator ofthe liowf'oi' water to the wheel; A pinion on this shaft a, acting` upon a rack' that isconnected with the gate, is the most usufal mode of'connectingithe regulator.

' ,In order to prevent the weight of the gate or any ofthe connecting'parts from turn-ing the shaft a, I. apply a'friction, consistingof thehub'c, u'pon the shaft a',fsecur,edfby the pin 2', and. receiving set-,screws'i 3, thatact upon clampinglsegmentshfi4, that"a1'c'placed within a grove 'arountlthe projecting collar-d,'upon one side of the bearing b. By this tneans the desired amount of friction can -be obtained, but the. parts can-be turned 'as hercafter'described.

The shaft aha-s', permanently aiiixed upon' it the-ratchet-xvheel f, and inl-'theiface ofthis ratchet-wheel is a i ciicularunder-cu't groove at e,into whichvnuts are introduced, taking the screws 6 of the adjustable flanged 'stopsgfgQ the anges of Vwhich are of a width reunite-about half the thickness 'of the ratchet-'wheel f. I ".lhesfoI stops g g can be moved around to anydesired points on"tl'e ratchet-inheelf, and clal'nped by the screws 6L On the otherv side ofthe'ratchetqvheelfto the stops gg is the'dskh, that has a ange, t, around rits edge',- l of a. w-iclth eqrual to about l1al' the thickness oi' the scid wheelj', andths'ange'is removed between the parts 7 and 8, as see-nI in fig. l. 4 e

This disk 'h might-'be forme'cl as an open wheel, or with arms carrying the iauge t atthesid'esf'ofithe opening between 7 and'S; n l

*In the side A.o't h, is a pin,'lc, projecting .into n curved slot in 'the stationary arm l, andA said slot limits the turning movement that may be communicated to this disk 7L by means of thelev'er-fmfol othervmechanism con? ne'eting with the governor. i

Around a sleeve, n, that extends from tho bearing bistlie hub-'of thepawl-car'riero, that'is continuously Aoscillaterl by 'the connecting-mdp to a crankl on `a shaft, g, thatis revolvedbfany suitableA connection to the shifting. v

l 'Upon the patri-carrier more thepal'wls r and -`s,`acted upon bysprings, and'i-lilaced with'their points towards each other.

` IWhentfheigovernor is revolvingo't the'designatedlspeed, th'e'ends lof thel pawls r and s Islideupon the Harige i, and do. not pass beyond the points'vfon, and.hence .do not move. the ratchet-whelei fJf-It the governor' is increased in speed,V the flange t isv moved by the -pin k, andthe opening'yinthoiange Abetween*Tand 8 comes into suchI avposlition that on'e ofthe 'pawls 1 s cannet uponv the teeth of theivheelj', turning that, and by theconnections moving the gute to'regulute the supply of' water, nnfl when che governor-balls fell to their standard speed., the turning ol' Llinilunge t prevents the further :Lotion of the puwl. f

lc is to be understood that when the speed of thegovernor is lessened, the parts operate in the reverse direction to wlnit they clo when the speed is increased.

If Llie speed 'of the water-wheel and parts is no1; sulieienbly regulated to produce n. reverse motion from the governor by the lime one of thestops y or g comes around beneath the pawl r or s than; is in action, saidetop, running under the snid puwl, will ruise it und arrest its further operation upon the rutclietteetl1; hence, by adjusting these stopsg und Lr/the point towhicii the sull-)ply of water cnn be opened or closed will be ldetern'iincfl, nnil Lhcreliy the regulator mnlle more unil'orm unil reliable in its ope/ration, thus preventing the. great fluctuations of speed usually resulting from L,he notion of regulators To water\ vlieels. I

What I elniui, and (lesire to secure by Letters Partout, is

'lhe adjustable stopsvgg, in eoinbinatiou with thepuwls 1' s, ratchet-wheel f and flange t, moved by connection to the governor, substuntviully ns ser; forth,

In witness whereof, I have hereunto set', my signature, this sixteenth doy of March, A. D. 1868.
